Creating Your App

Welcome to the Ember Tutorial!
This tutorial is meant to introduce basic Ember concepts while creating a professional looking application.
If you get stuck at any point during the tutorial, feel free to download https://github.com/ember-learn/super-rentals for a working example of the completed app.

You can install the latest version of ember-cli by following the Quick Start guide "Installing Ember" section.

Ember CLI, Ember's command line interface, provides a standard project
structure, a set of development tools, and an addon system.
This allows Ember developers to focus on building apps rather
than building the support structures that make them run.
From your command line, a quick ember --help shows
the commands Ember CLI provides. For more information on a specific command,
type ember help <command-name>.

Creating a New App

To create a new project using Ember CLI, use the new command. In preparation
for the tutorial in the next section, you can make an app called super-rentals.

ember new super-rentals

A new project will be created inside your current directory. You can now go to
your super-rentals project directory and start working on it.

cd super-rentals

Directory Structure

The new command generates a project structure with the following files and
directories:

app: This is where folders and files for models, components, routes,
templates and styles are stored. The majority of your coding on an Ember
project happens in this folder.

config: The config directory contains the environment.js where you can
configure settings for your app.

nodemodules / package.json: This directory and file are from npm.
npm is the package manager for Node.js. Ember is built with Node and uses a
variety of Node.js modules for operation. The package.json file maintains the
list of current npm dependencies for the app. Any Ember CLI
add-ons you install will also show up here. Packages listed in package.json
are installed in the nodemodules directory.

public: This directory contains assets such as images and fonts.

vendor: This directory is where front-end dependencies (such as JavaScript
or CSS) that are not managed by Bower go.

Ember CLI uses ECMAScript 2015 (ES2015 for short or previously known as ES6) modules to organize application
code.
For example, the line import Ember from 'ember'; gives us access to the actual
Ember.js library as the variable Ember. And the import config from
'./config/environment'; line gives us access to our app's configuration data
as the variable config. const is a way to declare a read-only variable to make
sure it is not accidentally reassigned elsewhere. At the end of the file,
export default Router; makes the Router variable defined in this file available
to other parts of the app.

The Development Server

Once we have a new project in place, we can confirm everything is working by
starting the Ember development server:

ember server

or, for short:

ember s

If we navigate to http://localhost:4200, we'll see the default welcome screen.
When we edit the app/templates/application.hbs file, we'll replace that content with our own.

The first thing we want to do in our new project is to remove the welcome screen.
We do this by simply opening up the application template file located at app/templates/application.hbs.

Once open, remove the component labeled {{welcome-page}}.
The application should now be a completely blank canvas to build our application on.
